In one embodiment, the present invention is a method and apparatus for detecting malware infection. One embodiment of a method for detecting a malware infection at a local host in a network, includes monitoring communications between the local host and one or more entities external to the network, generating a dialog warning if the communications include a transaction indicative of a malware infection, declaring a malware infection if, within a predefined period of time, the dialog warnings includes at least one dialog warning indicating a transaction initiated at the local host and at least one dialog warning indicating an additional transaction indicative of a malware infection, and outputting an infection profile for the local host.

Method and apparatus for detecting malware infection

A method for detecting malicious servers. The method includes analyzing network traffic data to generate a main similarity measure and a secondary similarity measure for each server pair found in the network traffic data, extracting a main subset and a secondary subset of servers based on the main similarity measure and the secondary similarity measure, identifying a server that belongs to the main subset and the secondary subset, and determining a suspicious score of the server based on at least a first similarity density measure of the main subset, a second similarity density measure of the secondary subset, and a commonality measure of the main subset and the secondary subset.

Systematic mining of associated server herds for uncovering malware and attack campaigns

A public licensing infrastructure (PLI) for a digital rights management (DRM) system is described. In an implementation, a method includes generating a formal license for content. The formal license includes a decryption key for decrypting the content and access rules for accessing the content. A plurality of license authorities is configured to provide a plurality of partial licenses. The plurality of partial licenses is combinable to form the formal license. Each license authority provides a respective partial license.
